On September 25, 2025, MEDIROM Healthcare Technologies Inc. announced a major deployment: it will integrate World ID’s ‘Orb’ humanness verification device across 100 Re.Ra.Ku relaxation studios in Japan, and plans to scale to 200 total locations.
This marks the largest installation of World ID in the country to date, signaling a leap forward in digital human verification infrastructure.
World ID is a protocol co-founded by Sam Altman and Alex Blania (via Tools for Humanity). It enables users to prove they are human (not AI) by validating ‘humanness’ via biometric or behavioral traits, while not storing personally identifying information.
The Orb device captures the necessary signals, issues a verified World ID via the World App, and integrates with compatible services that require human proofs.

Why This Is Not Just a Wellness Story, Its Tech Implications
At first glance, deploying World ID in massage/relaxation studios may seem tangential to core tech sectors. But in truth, this move has deeper significance for Japan’s technology industry and for any business that relies on digital authentication, identity, and AI governance.
1. Human Verification Becomes a Foundational Infrastructure
As generative AI, bots, deepfakes, and automated agents proliferate, distinguishing humans from machines becomes vital. Japan’s tech sector, including fintech, e-commerce, social platforms, health apps, and IoT services, stands to benefit from strong humanness authentication layers. The rollout by MEDIROM helps normalize these protocols in everyday contexts, accelerating trust in the underlying infrastructure.
2. Data Privacy and Trust in Biometrics
Japan has a robust legal environment around data protection (e.g. APPI). World ID’s promise of verifying humanness without storing identifying data is critical for regulatory adoption. Balancing verification and privacy can lower resistance from regulators and privacy-aware users. Tech companies in Japan must meet or surpass these standards to remain competitive.
3. Spillover Into Adjacent Tech Verticals
Once the base layer of verification is in place, developers can build services that require ‘human in the loop’ guarantees:
- DeFi / Web3 apps demanding sybil resistance
- Secure voting / governance systems
- AI-assisted platforms that need to ensure input or feedback comes from a real person
- Digital identity solutions for insurance, telemedicine, banking
In effect, MEDIROM’s deployment helps seed the ecosystem for these services by embedding World ID into everyday physical locations.
Business Impacts: Opportunities and Risks
Opportunities for Businesses Operating in Japan
Partnership paths: Technology vendors (authentication vendors, identity platforms) can partner with wellness chains, retail outlets, and service providers to embed World ID.
Platform integrations: SaaS players, mobile apps, gaming platforms can adopt World ID as a login or participation gate, reducing fraud and bots.
Differentiation & branding: Businesses that use this verification can call themselves ‘human-verified.’ This is attractive in industries that are at risk of fraud or fake reviews.
Key Risks and Challenges
User adoption friction: Customers often resist biometric or verification steps in low-stakes settings, like at a spa, especially if the experience feels awkward.
Privacy and public perception: Cameras or biometric signals attract scrutiny. Despite privacy safeguards, misunderstandings cause backlash.
Standards and Interoperability: Many humanness protocols are emerging. This creates fragmentation and slows down adoption. Businesses must support multiple standards or choose winners.
Regulatory uncertainty: Changes in data protection laws or new rulings on biometric authentication create compliance challenges.
Broader Impact on Japan’s Tech Industry
Japan’s tech sector has long emphasized reliability, security, and quality. The MEDIROM rollout may influence the following:
Rise in identity & trust startups: More startups may pivot or emerge to build services around World ID, humanness proofs, or identity-based services.
Acceleration of Web3 / blockchain use cases: As humanness proofs become available, decentralized protocols, token gating, DAO governance, and sybil-resistant networks could gain traction in Japan.
Cross-industry convergence: Healthcare, wellness, retail, entertainment, and tech industries may converge around identity services, for example, loyalty programs or patient verification using World ID.
Innovation in privacy-preserving tech: Japan’s tech community may push for zero-knowledge proofs, differential privacy, or federated learning to complement or compete with humanness verification systems.
結論
MEDIROM’s deployment of World ID technology across 100 (and eventually 200) Re.Ra.Ku studios is more than a wellness rollout. This move opens up a new layer of identity infrastructure in Japan. It connects physical services with digital verification. Tech companies will take advantage of the merging of identity, AI integrity, and privacy. This opens up new opportunities. However, they need to tackle big challenges in design, regulations, and adoption.
